In 4th grade, our first science unit is on waves, energy, and information. In this unit, 4th graders have "transformed" into young marine scientists investigating how bottlenose dolphins communicate. Bottlenose dolphins use unique "signature whistles" to identify and connect with one another, providing us with our first focus question.
We began our investigation with this focus question: How does a mother dolphin communicate with her calf across a distance? Through physical models, like spring toys and ropes, and the Sound Waves Simulation, students visualized how sound energy travels in waves. They created and revised sound diagrams, representing how sound moves through water. These tools helped them understand that sound travels as energy passed between particles—a concept not easily observed without modeling.
Why focus on sound and communication? Understanding waves and energy helps students grasp how sound underpins everyday life, from dolphin calls to digital messages. These investigations also build a foundation for future exploration of technologies like the internet and mobile devices. The engaging context of dolphin communication ignites curiosity, making abstract concepts like waves and energy tangible and memorable.
As 4th graders investigate, they gain not just scientific knowledge but also skills in modeling, reasoning, and communication. Our classroom is full of the excitement of discovery every day, as they uncover the hidden mechanics of sound and see the world in a new way.
